Which image sizes and aspect ratios does Google recommend for articles?

Definition: For Article structured data, Google recommends multiple high-resolution images that represent the article, with at least 50K pixels when width and height are multiplied, and the aspect ratios 16x9, 4x3, and 1x1.

Key facts

• Google's Article structured data documentation defines image as a repeated ImageObject or URL for an image representative of the article.
• The same documentation says image URLs must be crawlable and indexable, must represent the marked-up content, and must use a file format supported by Google Images.
• For best results, Google recommends multiple high-resolution images with a minimum of 50K pixels when width and height are multiplied.
• Google's documented aspect ratios for those images are 16x9, 4x3, and 1x1.
• Google's image SEO documentation advises avoiding an extreme aspect ratio and using high resolution when possible.

What does Google mean by a representative Article image?

The image property describes a URL or ImageObject for an image representative of the article. Google's Article guidance says to use images relevant to the article rather than logos or captions. It also says the image must represent the marked-up content and that its URL must be crawlable and indexable. The documentation therefore connects the image in the markup to the article a reader can access, rather than to a generic site asset.

Google's image SEO documentation says its image preview selection is completely automated and can use different sources. It lists primaryImageOfPage, an image attached to the main entity through mainEntity or mainEntityOfPage, and the og:image meta tag as ways to provide a preferred image. The Article page's image property remains the relevant structured data field for the article object.

What pixel area and aspect ratios are documented?

Google phrases the size guidance as a pixel area: the minimum is 50K pixels when multiplying width and height. This is an area threshold, so the page supplies no single width and height pair. It gives three ratios for multiple high-resolution images: 16x9, 4x3, and 1x1. The wording is a recommendation for best results.

The Article page shows the ratios as separate image URLs in JSON-LD:

"image": [
  "https://example.com/photos/1x1/photo.jpg",
  "https://example.com/photos/4x3/photo.jpg",
  "https://example.com/photos/16x9/photo.jpg"
]

Google's image guidance adds that a preferred image should be relevant and representative, should avoid an extreme aspect ratio, and should use high resolution if possible. Those points describe image choice around the Article markup; they do not add another fixed Article dimension.

How should the page deliver the images?

Google's image SEO documentation recommends responsive images with the picture element or the srcset attribute on an img element. It also recommends a fallback URL in src because some browsers and crawlers do not understand those responsive attributes. Its example is:

<img
  srcset="maine-coon-nap-320w.jpg 320w, maine-coon-nap-480w.jpg 480w, maine-coon-nap-800w.jpg 800w"
  sizes="(max-width: 320px) 280px, (max-width: 480px) 440px, 800px"
  src="maine-coon-nap-800w.jpg"
  alt="A watercolor illustration of a maine coon napping leisurely in front of a fireplace">

Google Search supports images referenced in an img element's src in BMP, GIF, JPEG, PNG, WebP, SVG, and AVIF formats. The Article guidance separately requires the image URL to be crawlable and indexable, so the markup and the delivered asset both need to be accessible to Google's systems.

FAQ

Does 50K pixels mean a 50K file?

No. Google's wording defines the figure by multiplying image width and height, so it refers to pixel area rather than a file-size limit.

Does Google give one exact width and height?

Google gives the pixel-area minimum and the three aspect ratios, but the Article documentation does not give one fixed width and height pair.

Must every Article image use all three ratios?

The documentation recommends providing multiple high-resolution images with the 16x9, 4x3, and 1x1 ratios for best results. It presents those ratios as recommendations in the Article image guidance.
